For romances that not only involve the use of fantastic plot elements, but are literally impossible to pull off unless one or both parties are chronically defying the laws of physics, traveling through time, reality warping, dimension hopping, or defying culturally accepted norms and standards regarding the mingling of fantastic, non-fantastic, or other fantastic races.
If a character is Trapped in Another World
and then gets embroiled in such a romance, they often end up saying I Choose to Stay
. If they are forced apart, or decide to return to their own worlds
, then they are Star-Crossed Lovers
. They may still get a Doppelgänger Replacement Love Interest
back at home. Such relationships often result in the creation of a Half-Human Hybrid

Anime and Manga
- The Vision of Escaflowne.
- In Fushigi Yuugi, Miaka and Tamahome.
- Eureka Seven has this as the driving force between the two leads.
- InuYasha: The main story is set 500 years in the past, which is the time period Inuyasha belongs to. Kagome, however, is a girl of the modern age who accidentally finds a way to travel back in time to Inuyasha's period. Without that time travelling, they'd never have met. This is made even more complicated by the fact that the reason Kagome can time travel is due to the desires of the woman she is a reincarnation of: Kikyou, who died 50 years before the main story's setting, was Inuyasha's first love and guardian to the Shikon Jewel. Without her duty to the jewel and her desire to see Inuyasha one last time as she died, Kagome would never have been able to travel through time nor would she have inherited guardianship of the jewel that brings her and Inuyasha together.
- Kikyou's "desire to see Inuyasha" seems more like a retconn on Rumiko Takakhashi's part rather than an actual desire on the part of the character, considering her last wish was to take the jewel from Inuyasha's "evil" hands and she specifically wished to never see him again. And went straight to killing him for a long time after her resurrection. Add to that the generally cold way she treats him after being brought back, not lifting a finger to protect him and even putting his life in danger several times, her "wish" is seems more like a retcon designed to create more sympathy for her. Either way it was the wish of the jewel not Kikyou that brought Kagome back in time and Kagome herself states her heart is her own. Inuyasha also states that he was born for Kagome and his feelings for her have nothing to do with Kikyou.
- In RahXephon, one of these drives the entire plot.
- To explain further (massive spoilers ahead): Ayato and Haruka were middle-school sweethearts, but the impenetrable Tokyo Jupiter field went up while she was on vacation, trapping him inside and her out when they're fourteen. Thanks to the field's time-dilation effects, three years pass for him and fifteen for her. Thus, Haruka is twelve years older than him when she manages to rescue him from Tokyo. Furthermore, he has lost all memory of her (and technically isn't even human anymore). She, however, has spent the whole time pining for him. Eventually, he once again falls in love with her, and that love drives him to use his Humongous Mecha's full potential and become a god. In the end, he recreates the world so that the two of them can be together.
- The fact that it is heavily influenced by the short story The Dandelion Girl helps explain a lot.
- In Voices of a Distant Star, the teenaged romantic leads are separated by Faster-Than-Light Travel without any corresponding method of faster-than-light communication, so that by the end, the 15-year-old girl's text messages aren't received by her boyfriend until he's 24 and beginning to move on. It is every bit as heartbreaking as it sounds.
- Yami to Boushi to Hon no Tabibito: When your girlfriend is the axis mundi and you're a normal schoolgirl (for a given value of normal), romance is literally impossible to maintain. It's possible to meet her again, just... not in the capacity of lovers.

- Puella Magi Madoka Magica: Congratulations, your girlfriend has broken the Vicious Cycle that killed her repeatedly, but now she no longer exists in the space-time continuum! You can still hear her voice, though.

The Doctor, however, refuses to accept this and spends the next 4.5 billion years on a Batman Gambit to change history and bring Clara back to life, an action that threatens to destroy all of creation. Ultimately, he is partially successful as Clara is extracted from time one heartbeat before her death, rendering her immortal. Unfortunately, despite her willingness to stay with the Doctor forever, their relationship is too dangerous - and she must someday return to the point of her death - and the Doctor accepts a memory wipe in order to keep her safe and regain his sanity.
